Answer: Please see below
Explanation:
Depletion expense = Initial price Purchase - Residual value / Total number of units.
$1,500,000 - $250,000/ 2,000,000 = 0.0625 per ton
if 150,000 tons of ore are mined,
Depletion expense = depletion per ton x units mined
0.625 x 150,000=$93,750
journal entry to record the depletion is:
Account Debit Credit
Depletion expense $93,750
Accumulated Depreciation $93,750
